i font-Lock.

To all whom it ma'y concern-j g Be it known that I, Isaac ELVIN' Dram MoNma citizen of the United States, res ding at Newkirk, inthe county of Kay and State of Oklahoma, have invented certain new and useful lmprovements in Fuel- Locks, of which th tion. This invention relates to fuel locks for internal combustion and like motors and 1t is the principal object of the inventlon to provide a fuel lock especially adapted for use in connection with motor driven vehicles whereby the flow of fuel through the lntake manifold to.the motor can be discontinued by the operatorwhen leaving the vehicle and locked in order that the theft of the same will be prevented during his absence.

It is also an object of the invention to provide a simple, durable and compact locking means for the fuel controlled valves whereby the same can be locked in closed position and freely opened when desired.

Other objects will be in part obvlous and in part pointed out hereinafter.

The invention consists, furthermore, 1n the novel arrangement and combination of the parts of the look, as well as in the details of the construction of the same, all of which will be more fully described in the then finally embodied in the clauses of the'claim, which are appended to the specification and which orm an essential part of the same. The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a valve provlded with the improved lock, portions of the same being in section.

Fig. 2 is a horizontal section therethrough, and,

Fig. 3 is a valve spindle.

Having more particular reference to the drawings and in connection with which like reference characters will designate corre sponding parts throughout the several views thereof, 1 represents the base plate or body of the valve, the same being provided with a centrally disposed opening 2 and other smaller openings 3, which as will be understood, receive bolts or like fastening devices therethrough when the said plate is interposed in the intaker anifold of a combustion detail in perspective of the motor.

e following isa specifies; through Specification of Letters Patent. Patented July 29, 1919. i w wifi I Application filed November 16,1917.- Serial No. 202,343,

Fo'fmed integralwith the upper portion of the plate 1 is'a casing 4 having oppositely disposed vertical bores formed therein, one of whiclrrotatably receivesthe spindle 5 of the usual butterfly type of valve 6 mountedv so as to contn 1. the vpassage of f uel the ni'n'g same the manifold and combustion motor. In this connection, it is to be noted that the spindle 5 is provided with a barrel 7, the same being of a size and shape complemental to the bore and being snugly received thereby. A pocket or keeper 8 is formed in the peripheral surface of the barrel 7 and is adapted to aline with a way 9 formed in the side wall of the said bore and communicating with the adjacent bore.

Rotatably mounted in the remaining bore is the barrel element 10 of a lock, the lower portion of which is recessed as at 11 and has pivotally mounted therein a bolt or locking pin 12 adapted to be passed through the way into engagement with the keeper 8, at times, said pin being formed with a curved bearing head 12 engaged by a spring 12"; the tendency of Which is to move the free end of the pin outwardly so that it will normally tend to engage in the way 9 and the keeper 8 upon rotation of the barrel element. A key receiving way may be andpreferably is formed in the upper portion of the barrel 10 and obviously, permits the introduction of a key thereinto in order that the said barrel may be turned. Thus, when the barrel 10 is turned clockwise the locking pin 12 which is pivotally mounted thereon will be caused to move outwardly into engagement with the way 9, by reason of a spring 12 arranged in the said recessed portion 11 and normally bearing thereon. As a consequence, the locking pin will pass into engagement with the keeper 8 and thereby prevent the rotation of the butterfly valve 6.

From the foregoing, it will be readily understood by those skilled in the art that I have provided an efficient form of fuel lock whereby the supply of fuel through an intake manifold to a combustion or like motor may be discontinued at will by the operator and locked in its closed position to prevent tampering or undue operation of the same by unauthorized persons. The device, by reason of its positive operation and compact form is especially adapted for use in connection with motor driven vehicle,

' affording an efiective means for preventing theft' 'of the vehicle during the absence of the operator or owner. I r

7 r Manifestly; the construction shown is ca- 1 5 pable of considerable modification and-such;

7 10 In combination withthe fuel feed pipe of a motor, a valve casing interposed therein, acasingfarranged on the valve casing having a plurality of vertically disposed bores therein, one of said bores receiving a valve 15 spindle therein, said valve spindle having Copies of this patent may be obtained for five cents each, by addressing the Commissioner of r latents,

'move the free end of the locking pin out a keeper therein; a rotatable barrel in the remainlng bore having a recessed portion, a locking pin formed with a curved bearing head pivoted to'the barrel and havingsaid bearing head engaged in the recessed portion thereof, and a spring engaged I with the head normally tending to curved bearin Wardly througha bore communicating With said vertically'disposed'bores into the first bore and in engagement at times with said keeper upon rotation of the barrel. 7 V

In testlmony whereof, I ailix my signature. hereto.
